REVOLVINQ RAZOR.

To all whom it may concern:

Be it known that I, WILLIAM E. Travers,

- a citizen of the United States, residing at Oakland, in the county ofAlameda and State of California, have invented new and usefulImprovements in Revolving Razors,

. of which the following is a specification.

which is so designed and constructed as to be easily and readilyoperated.

A further object is to provide a razor of the above character, in whichinterchangeable razor blades are employed, and which is so arranged thatthe blade may be quickly attached or removed.

Theinvention consists of the parts and the combination and constructlonof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure 1 is aperspective view of the invention, showing the manner of driving same.Fig. 2 is a vertical section. Fig. 3 is a detail in perspective, showingthe blade guard construction. I Fig. 4 is a cross section on the lineXX, Fig. 2. Fig. 5 is a cross section on the lines Y-Y, Fig. 2. Fig. 6is a cross section showing a modified form of mounting the razor blade.Fig. 7 is a perspective view of a blade.

In .he drawings, the invention .is shown as embodying a tubular handleA, in which is mounted a revoluble shaft2, which extends longitudinallythrough the handle A, and is supported therein on bushings 3 and 3'. 7

The outer end of the shaft 2 is connected to a flexible drive shaft 4,which is attached Acylindrical razor guard '10 is adapted to be placed,overthe outer end of the shaft 2 Specification of Letters Iatent.Application filed February 21, 1911. Serial No. 809,976.

with its inner end resting upon the outwardly projecting portion andwithin the upwardly rojecting portion of the flange 8 on the co lar. 7.-This razor guard 10 is slotted longitudinally, at 11, through which thecutting edge of a flat razor blade 12 extends, as shown in Figs. 4:, 5and 6. This blade 12 is designed to be inserted in the razor guard 10,between the inner arcural surface of the guard. and the shaft 2., withthe rear edge 0 the blade resting against a yieldable abutment 13mounted on the razor guard 10.

Means are rovided for securing the blade 12 against bemg accidentallyloosened or displaced in the razor guard 10 and to prevent its beingthrown outward th 11 by thecentrifugal force exerted by the rapidrotation of the razor guard 10 and shaft 2. This is accomplishedasfollowsz- The outer end of the shaft 2 is threaded to receive a cap15, which, when threaded on' the shaft 2, extends over 'the outer faceof the upper end of the razor guard. 10. The razor blade 12 extends thelength of .the

razor guard 10 and is retained therein bymeans of the cap-member 15 andthe upwardly projecting flan e 8, the spring-member 13 holding theblafposition in the guard 10. The edge of the slot 11 opposite the cuttingedge of the blade 12 is beveled to form a slight recess adjacent theblade, and portions of the razor guard are cut away on this beveled edgeof the slot 11 to form a series of transversely disposed teeth 16. w

. In operation, the razor blade',12 is inserted within the tubular razorguard 10, the cap 15 being removed for that purpose,

' the cap 15 beingthen re laced on the tubular razor guard 10 and s aft2 to clamp the former upon the latter and secure the blade 12 within theguard 10. The motor 6 is rough the slot e in its forward-most then setin motion to rotate the shaft 2-- The razor guard 10 being placedagainst the face, the razor blade 12 willv travel across thesurface ofthe skin in a curved direction; that is to say, approaching the surfaceof the skin at a downwardly curved slope and leaving it in an outwardlycurved direction, thus tending to have a clean cut action. In caseswhere it is not convenient to rotate the razor bladeby motive power, itmay be converted into a hand razor by disconnecting the flexible shaft 4from the shaft 2 and locking the latter to the handle A, a thum-screwthreaded on the lower end of the shaft 2 being provided forthis purpose.In some instances it may be desirable to rotate the razor blade of theguard 10, in which event the blade is attached to the shaft 2, as shownin Fig. 6,

and the guard is mounted stationary on the handle Having thus describedmy invention, what I claim and desire to secure by Lettors-Patent, is

1. In a razor, a rotatable, cylindrical razor guard, a razor bladedetachably mounted therein, a revoluble shaft on which said razor guardis removably mounted, a hand hold through which said revoluble shaftextends, a flexible drive shaft con- 1 nected to said revoluble shaft,said shaft having a collar with an outwardly projecting tubular flange,and said guard having its inner end fitting said flange and abuttingsaid collar, and means for rotating said flexible shaft to rotate saidrazor guard and blade.

2. In a razor, the combination of a handle, a shaft extendinglongitudinally therethrough, means for rotating said shaft, means forretaining said shaft in said handle, a cylindrical member removablyattached 'to said shaft, a detachable razor blade, a yieldingspring-pressed abutment fixed to the inner wall of the cylinder having afree end to receive the back of the blade, and means for clamping saidblade in said cylinder, said clamping means embodying a cap threaded onthe shaft and having projections adapted to extend over the upper end ofsaid cylinder.

3. In a razor, the combination of a handle, a revoluble shaft extendinglongitudinally therethrough, means for retaining said shaft in saidhandle, a cylindrical member removably attached to said shaft, adetachable razor blade, means for clamping said blade in said cylinder,said clam 111g means binding said cylinder to said shaft, said meansembodying a cap threaded on the shaft and having projection adapted 'toextend over the upper end of said cylinder, and means for rotating saidrevoluble shaft to rotate said cylinder and razor blade.

4. In a razor, the combination of a handle, a revoluble shaft extendinglongitudinally therethrough, means for retaining said shaft in saidhandle, a longitudinally slotted cylindrical member removably attachedto said shaft, a razor blade, extending at an angle across the chamberof the cylinder, said cylinder having a spring seat 'for the back of theblade, means for de- G.
